As a welding expert with extensive experience in various welding techniques, I can provide you with a comprehensive answer regarding the welding of aluminum. Aluminum is a unique material that poses specific challenges due to its high thermal conductivity, high reflectivity, and affinity for oxygen, which can lead to the formation of a tenacious oxide layer on its surface. This oxide layer can interfere with the welding process, making aluminum welding a delicate and precise task.
When it comes to welding aluminum, there are several methods available, including Shielded Metal Arc Welding (SMAW), also known as stick welding, Gas Metal Arc Welding (GMAW), also known as MIG welding, and Gas Tungsten Arc Welding (GTAW), also known as TIG welding. Each of these methods has its advantages and disadvantages, and the choice of method can depend on factors such as the thickness of the material, the desired quality of the weld, and the specific application.
Stick Welding (SMAW): This is a manual arc welding process that uses a consumable electrode coated with flux to lay the weld. The flux coating of the electrode provides shielding from the atmosphere, which is crucial when welding aluminum. The DC stick welder, as you mentioned, is capable of welding aluminum. It can be effective in breezy conditions due to the flux coating, which helps to protect the weld pool from contamination. However, the controllability of stick welding is somewhat limited compared to other methods, and it requires a skilled operator to achieve a high-quality weld. The process can be slower due to the need to frequently change the electrodes and the fact that it is a manual process.
MIG Welding (GMAW): MIG welding is a semi-automatic or automatic process that uses a continuously fed consumable wire electrode. It is known for its speed and ease of use, especially for thicker materials and longer welds. However, MIG welding with DC is indeed faster but less controllable when it comes to welding aluminum without adding filler metal. The process can be challenging in breezy conditions due to the potential for contamination from the wind affecting the weld quality. MIG welding also requires a shielding gas, often a mixture of argon and helium, to protect the weld pool.
TIG Welding (GTAW): TIG welding is a more precise and controllable process that uses a non-consumable tungsten electrode and a separate filler material if needed. It is highly versatile and can produce high-quality welds on thin materials. However, TIG welding is generally slower than MIG welding and requires a high level of skill from the operator. It is also sensitive to wind and breeze, which can disrupt the shielding atmosphere and lead to contamination of the weld.
In terms of welding aluminum, each method has its place. Stick welding with a DC welder can be a viable option, especially in situations where other methods are not feasible or when a skilled operator is available. It is important to note that while stick welding can be done in breezy conditions, it is always preferable to perform welding in a controlled environment to ensure the best possible results.
When welding aluminum, regardless of the method chosen, it is essential to take precautions such as cleaning the material thoroughly to remove any oxides or contaminants, using the correct shielding gases, and maintaining a proper welding technique to achieve a strong and clean weld.
In summary, while MIG and TIG welding have their advantages, stick welding with a DC welder can indeed be used to weld aluminum effectively, especially when the conditions are not ideal for other methods. The key to successful aluminum welding lies in understanding the material, selecting the appropriate welding process, and applying the necessary techniques and precautions.

MIG, which is DC, is much faster than TIG, but it is not nearly as controllable because you cannot melt the base metal without adding filler metal. ... Neither TIG nor MIG can weld aluminum in breezy conditions. However, stick welding aluminum is possible with a DC stick welder and it actually works better than I expected.
